IMPROVEMENT IN'CHURNS.

The Schedule referred to in these Letters Patent and making part of tl1'e same.

To all whom e't may concern:

Be it known that I, THOMAS S. N Ur'rnn, of Harrisburg, in the county of Franklin, and State of Ollio, have invented new and useful Improvements in Chin-ns;

and I do hereby declare that the following is a full,l

clear, and enact description of my i11\;entio11, reference being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked the1'eon, of which drawingshigure lis an elevation vof my improved churn. v Allfigure 2 is an elevation of gearing and dasher,..de tached from churn-box. v

Figure is a plan of chum-box. Figure 4 is lau elevation of the upper part of the standard side of churn-box. I

Figure 5 is an end view of dasher. The nature of my invention consists in certain iin- `provements in that class of churns operated by an upright rotary dasher; .said improvements consisting,

lirst, in the novel construction of the dasher, i'vhereby the violent-agitation of the cream -is effected, and the operation of churning much facilitated; and secondly, in the novel construction al 1d combination of the several parts ofthe churn-mechanism and box, whereby greater 4facilities are afforded for the construction and adjustment vof the several parts'of the machine, and the whole churn is made of a very firm and solid character.

lo enable others skilled in the art to make'and use my intention, I will proceed'to describe its construction and operation. v

The body A of my churn is of the general form shown, having a foot-base and knobs, for convenience in'lifting, when desired.

'lhe sides B B are extended above the balance of the body, and are provided with a slot, F, as shown in iig. 4, in which -iit the gearing-flame slides G G, as shown in iig. 1.

A hearing-spindle, E, fin' the dasher is secured'in the bottom of the churn-body A, and the covers C C are arranged as shown, to cover over the cream while being churned. Y

lhe principal part, H, of the gearing-frame is cons veniently made of cast-iron, but may be made of anyother suitable material, and has the arms lt h at its ends, at the tops of which are the boxes c o, in which the main shaft I is placed.

. This shaft is extended out beyond the side B of the churn, either on one side, as shown in drawing, or ou both sides, if desired, and has the crank It at its end, as shown, or a crank may be used at each end, where a large amount of power is required.

The large bevel-gear wheel J is secured on the shaft I, and meshes intorthe bevel-pinion K on the dashershaft L, which is arranged in a box in the frame-piece H, and has its upper end pivoted in the arm l, on the piece H, as shown in figs. 1 and 2.

The gearing-frame slides'G are made of wood,rand are of the general, form shown in figs'. 2 and 6, being provided with an end plate, g, which stands on the outside of the slotted Aarms B B when the frame is on the-churn, as shown in g. 1v.

.lhe thickness oflthe main part of thel slide Gr is made to Vconform to the distance between the arms 7L of the gearing-frame andthe slotted arms B ofthe churn-box A, while thewidth and'thickness of the narrow part of-saidslide are made to conform to the width and breadth of the slot F in the arm B, from which it is readily seen that the Yflame h H 71 with its accontpanying shafts .,I. L, and bevel-gears JA K, can be used for various sizes of churn-boxes, by simply changing l the size of the wooden slides G (i.

lhc dashcr-shait M is provided with a metallic top,

on, the end of which ts =into a hole in the shaftL,"

whercit is secured by a pin, a.

This dasher-shaft M has a hole, n, formed in its lower end, which sets over the bearing-spil'ulle E, which thus forms a bottom bearing for the dasher.

'lhe dasher N O I Q is formed of the upper and lower slats, N Q, which have their ends formed into the triangularsections shown, and the central slats, O P, which have their ends formed into the-diamond-shaped sections shown, and which are so arranged as to bring' these arms into the positions with respect to each other shown' in 1i g. 5, thc upper and lower edges of any two contiguous slats N O or O P being so arranged as to be in nearly the same horizontal plane.

The number of arms O l to be used may be' varied to suit the depth of cream in the churn, the upper and lower slats, N Q, of thc fonn shown, being used in all cases.

lhese slats are secured on the dasher-shaft M, by passing said shaft through holes in the slat, and then securing the slats by wooden pins, driven through' them and the dasher-shaft. i-

From the foregoing descriptiomit will be readily'.

seen that'by turning the crank It, a rapid rotary movement will be imparted to the dasher N O Q, which will force the cream up and down the advancing inclined faces offsaid arms, and through the spaces between said'arms, which will produ'ce 'a violent lateral and vertical inotion of the particles of said cream, and thus insure a rapid churning of the butter.

On the completion of the churning, the pin c can be taken out, when the gearing and frame J K H can be readily lifted from the arms B B.

The covers l C can then be taken olf, and the flasher M N Q lifted out, when the churn-box willbe in convenient shape for removing the butter.

Having thus fully described my invention,

What I claim therein as new, and desire to secure by Letters Patent, is

l. The dasher M N Q, herein described, composed of the shaft M, upper and lower slats N Q, with arms of tzmgulzn cross-section, and two or more central sluts O P, with :trmsof diamond cross-section, when l R, bevebgezns J K, dashenshaft L M, with `pinned connection q, and bearing-spindle E and flasher N O P Q, the several parts being constructed and arranged with respect to eawh other substantially its is herein specified.

As evidence that I claim the foregoing, I have hereunto set my hand, this 17th day of April, 1869.
